Were you wondering too?
In case that was not covered yet (as I see lot of comments about that)
Capacitive buttons on the +OnePlus device? Not necessarily, you actually have the choice!

+Carl Pei showed that in the screenshots he published a few days ago − with and without: disabling the capacitive buttons in settings make standard Android software buttons appear on screen.

At the same time, capacitive buttons are turned off entirely.
You can't even guess there were here.
Also, you can switch between one configuration or the other anytime. The change is instant (no reboot necessary)

As the bottom bezel behind the display is used for components and battery, the room is not actually lost.
In software button mode, this inert bezel becomes a good place for your fingers when reading, holding the device with  a single hand.

That's a simple clever little trick.
Software buttons all the way for me! Especially with KitKat immersive mode.

I actually love having the choice. There is always a scenario where one or the other solution worked better for me. It's way faster for me to use the capacitive buttons while navigating switching between applications without using part of my screen and when playing game for example you just don't want them there on screen buttons are best... So again we have choice

+François Simond anything that you have time for could help. Any books, resources, website recommendations that you find interesting/motivating would help. Just any interesting resources to get us college students more interested/motivated in development would be helpful honestly.

I really just like asking devs that I admire for any type of collaboration because it motivates me, which makes me a more engaged organizer.

It also helps my GDG chapter grow and helps it's members focus on projects that will help them be successful in the future.

In my experience, any information that you could provide, no matter how small, can help us achieve our dream of becoming successful programmers.

Here's my take on +OPPO Super Zoom feature, as it's the hot device analyzed by the press right now.
You'll find a few ideas on how to make the most of it.

+Erica Griffin sent me whole albums of samples she took with her Find 7a review device:
with/without Super Zoom + comparison shots with the Galaxy S5.
Thanks :)

To my knowledge, +OPPO Find 7a is the first device implementing 
Superresolution algorithms this way.
We've seen multiple exposure noise reduction like Samsung Night mode, but increasing the amount of resolution is something new.

Take a look at Superresolution page on Wikipedia:

I'm also linking to +Taylor Martin article on +Pocketnow which shares examples.

Now, from the samples I played with, two things appear clearly:

1/ despite being taken from the same lens and sensor, Super Zoom images contain more data. The resolution is higher, more textures are preserved.

2/ the 50MP output is soft. When viewed at 100% on a computer monitor, it look like a blown-up lower resolution image (albeit with a fine algorithm that look like lens / out of focus blur as it introduce no trace of pixelization).
If you downsize those Super Zoom pictures like with a Lanczos algorithm you gain back some pixel sharpness at 100% as you un-zoom, but the image still stays somewhat soft.

How comes?
Well the reason is simple:
Image resizing algorithms are tuned to be introduce no aliasing or other artifacts, while preserving the original look of the source faithfully.
For this reason, if you downsize a 50MP to 13MP, the soft input results in a comparably soft output.

To fix that, you can use several approaches: typically

- Sharpen the 50MP image before downsizing it, in a way that the large image would appear sharp.
As 50MP is a lot from the 13MP bayer sensor, this sharpened stage might exhibit various small-size artifacts, but that's no big deal. Also, remember than like every other sensor, 13MP is actually 13 mega colored subpixels, see

I'm not inventing anything here: many camera manufacturer already use this method and optimize the JPEG output of their camera to go through downsizing.

One example: obvious sharpening halos in Canon JPEG camera output, here from the brand new G1X Mark II :
Full size:

During downsizing, sharpening artifacts of various kind will actually compensate for the softness of the full size source.

- Sharpen the downsized image
That can work too.
Be careful tho that your sharpening algorithm and parameters wont introduce visible artifacts then, as it's your final output you're playing with ;)

-A more complex approach
Some like using 2 passes for that: downsizing the original a bit to gain some per pixel sharpness, sharpen this step just right, then downsize again to the final resolution.

Downsizing and sharpening is the approach used by Nokia in their PureView system. In this case, the additional detail is not gathered by multiple exposure but by a higher resolution sensor.
My opinion is that they over-do it a bit: the regular output is only 5MP.
Real 5MP with maximum per-pixel sharpness but still, a fair amount of real information is gone.

Using the Super Zoom feature, you gain additional detail in the shot thanks to the Superresolution algorithm working with data from multiple exposures.
+OPPO camera exports the whole thing as a very high resolution image instead of a downsized version.
This way, you can make your own image out of it.

In my tests, I found the result once tuned to taste ending with a very analog/filmic look instead of regular digital imaging. That's interesting.

To me the biggest benefit is this organic look as pixels disappear, and the higher amount of texture detail even when shooting in low light.
It's very different from what we're used to see in cameras' JPEG output today.

But I will recommend you to process those files before publishing them.
Oppo announced the Find 7, capable of taking 50-megapixel images, last week. Ready why the Find 7 camera has us exciting for mobile cameras of the future!

+Casey Meighan this write-up was not mentioning depth of field once.
Super-resolution doesn't invent details, it uses math to see them beside sensor and even lens limitations.
Doesn't it remind you a certain telescope?
Please refer to the wikipedia article.

Inspired by +Martin Mal photo new +OnePlus samples, I wrote here about smartphone cameras and colors.

You know I'm passionate about display calibration already:
well it's the same with cameras ;)

The title reminds me of something.... ;-)
Well played +Android Police !

+Koushik Dutta : your interview here makes easy to understand why you chose to leave +Cyanogen Inc., especially for me as long-time independent developer.

It makes sense given the fact your strategy has been to continue developing new apps that are capable of doing everything you need without requirement to modify the system frameworks or lower levels.
And those apps like Helium, Allcast and Mirror are anything but obsolete and won't be before years it seems.

When you release stuff out here, it's hard to give it up because of a lack of time. A dev can be really attached to his creation, dedicated, he won't want to disappoint masses of users who trusted him.

This also why since I knew I would have to find a job with a US company to move and live there in good condition, I anticipated and focused on pure R&D instead of apps releases.
Compared to Koush, my contributions are relying on hardware and lowest levels layers why working as close as possible to manufacturers has been my target for years.

Thanks +Koushik Dutta for sharing your story!

I've been in the same field as you but arrived later, you've always been an inspiration, I would have loved being colleagues and continue learning from your experience this way.
But you made a logical choice here instead of staying trapped in an impossible contradiction.

See you in Seattle in a few months!
Hey, I did an interview!

Read the comments... Man, people really love their SD Cards...

$299 USD for the 16GB +OnePlus ?!
Uh wow okay that's a huge lot of bang for the buck.

I didn't expect this, it's a very good news :)

Last gen smartphones with 4K Ultra HD  and 4K DCI recording capabilities might be the reason why asymmetric landine Internet access technologies will  have to go bye-bye.

Not sure how many.. days it will take!

+François Simond Turk Telekom owns landline phone network in the whole country.
ADSL internet providers are just reselling Telekom's landline ADSL.
So, Turk Telekom says I'm the boss, I make the rules.

Because I will continue blogging as myself, and because my fiancée +Erica Griffin is a smartphone analyst making reviews on YouTube, here's an experiment:

I'll post as +Francois@Cyanogen Inc. every-time the topic is related to my new job at +Cyanogen Inc. 
This way it announces when by definition being 100% not biased is not possible, by definition.

Many Google employees post as themselves mixing personal and professional and nobody is shocked by that.
Maybe it's an unnecessary distinction as ethic statement?

Any objection or suggestion?
These screenshots shared by a +OnePlus exec might be either from an old be or a theme.

What I've seen looks more modern than that :)
− In case you were wondering about those color accents in the status bar!
Earlier tonight we saw a supposed leak of the upcoming OnePlus One. The leak included press renders of the phone, a variety of back covers, and supposedly depicted the phones upcoming UI. Carl Pei of OnePlus took to the official OnePlus forums moments ago to put an end to the rumors running rampant this evening.

Well done, simple but very real-world oriented camera comparison shootout between the iPhone 5s, Galaxy S5 and the M8.

It leaves out the resolution & details aspect as images are downsized, which is representative of some Web exports.
- only some because an increasing number of social media provide a high resolution Full-screen experience now, allowing to zoom as well.

Results are self-explanatory, no comment needed :-)

One test I wish that would be done is a comparison between the M8 and a 4 years old 5Mpixel Android phone or tablet.
One that was taking good pictures.

Last year, with Erica's m7 I shot some candid to compare the Galaxy S I9000 (first gen) camera with HTC OIS 4Mpixel module.
Results including in low light were quite amusing.
Then I did the same comparing to a 3Mpixel Galaxy Tab 10.1... wish I kept the pics.

Looked at them on PC / iPhone / LG G2 and the iPhone and Samsung both are good cameras. I just see an all around better picture with the iPhone and with the iPhone its not filled with gimmicks etc. It does the job of a camera. With less megapixels. And I don't see a big improvement from my Note 3 camera to the S5 camera. There's nothing there to wow me into grabbing on to Samsung and definitely not HTC's camera. Its just bad.
